First solar collector created by Swiss scientist named Horace-Benedict de Saussure in 1767, he take an insulated box enclosed with three layers of glass which suck up heat energy. After that Saussure’s box became famous and widely known as the first solar oven, getting temperatures of 230 degrees Fahrenheit. After that in 1839 a most important landmark in the progression of solar energy occurs with the significant of the photovoltaic effect by a French scientist Edmond Becquerel. In this he used two electrodes placed in an electrolyte and then exposing it to the light and results is tremendous electricity increased a lot. After that lots of experiment are occurred by various scientists at time to time and modified our solar energy system to produce more electricity from solar energy. But now a day’s also in this field various experiments are doing by a scientist, how to utilize maximum solar energy which is available on the earth.
In 1873, Willoughby Smith discovered photoconductivity of a material known as selenium. In 1887 there was the discovery of the ultraviolet ray capacity to cause a spark jump between two electrodes and this was done by Heinrich Hertz. In 1891 the first solar heater was created. In 1893 the first solar cell was introduced. In 1908 William J. Baileys invented a copper collector which was constructed using copper coils and boxes. In 1958, solar energy was used in space. In the 1970′s, Exxon Corporation designed an efficient solar panel which was less costly to manufacture. Less cost manufacturing process of solar panel became the major milestone in the history of solar energy. In 1977 the US government embraced the use of solar energy by launching the Solar Energy Research Institute. In 1981, Paul Macready produced the first solar powered aircraft. in the year 1982 there was the development of the first solar powered cars in Australia. In 1999 the largest plant was developed producing more than 20 kilowatts.
In 1999, the most proficient solar cell was developed with a photo-voltaic efficiency of 36 percent, now a day we produce 200 megawatts to 600 megawatts electricity from solar energy like in India’s Gujarat Solar Park, a compilation of solar farms spotted around the Gujarat region, show a mutual installed capacity of 605 megawatts and Golmud Solar Park in China, with an installed capacity of 200 megawatts.
